Glutamyl-prolyl-tRNA synthetase 1 (EPRS1) is known to associated with fibrosis through its catalytic activity to produce prolyl-tRNA. Although its catalytic inhibitor halofuginone (HF) has been known to inhibit the TGF-β pathway as well as to reduce prolyl-tRNA production for the control of fibrosis, the underlying mechanism how EPRS1 regulates the TGF-β pathway was not fully understood. Here, we show a noncatalytic function of EPRS1 in controlling the TGF-β pathway and hepatic stellate cell activation via its interaction with TGF-β receptor I (TβRI).

In the operating room, unanticipated difficult intubation can occur and anesthesiologists can experience challenging situations. Undiagnosed tracheal stenosis caused by congenital factors, trauma, tumors, or post-intubation injury, can make advancing the endotracheal tube difficult. We present an adult patient in whom we were unable to pass an endotracheal tube into the trachea.

Despite the importance of glucose and amino acids for energy metabolism, interactions between the two nutrients are not well understood. We provide evidence for a role of leucyl-tRNA synthetase 1 (LARS1) in glucose-dependent control of leucine usage. Upon glucose starvation, LARS1 was phosphorylated by Unc-51 like autophagy activating kinase 1 (ULK1) at the residues crucial for leucine binding.

Background: Overactivation of inflammatory cells, including macrophages and neutrophils, is associated with acute lung injury. BMS-470539 is a selective agonist of melanocortin 1 receptor, which triggers the inhibition of proinflammatory responses, suppressing neutrophil infiltration and protecting tissue. This study evaluated the effects of BMS-470539 on lipopolysaccharide-induced acute lung injury in a mouse model.

Background: Chemotherapy-induced neuropathic pain (CINP) is a serious side effect of chemotherapy. Korean Red Ginseng (KRG) is a popular herbal medicine in Asian countries. We examined the therapeutic potential of intrathecally administered KRG for CINP and clarified the mechanisms of action with regard to 5-hydroxytryptamine (5-HT)7 receptor at the spinal level.

Purpose: The purpose of this study was to identify nursing interventions for the postpartum breast care of mothers and determine the effectiveness of interventions for breast pain and engorgement by systematic review.

Methods: Eight national and international databases were reviewed to retrieve and collect randomized controlled trial and controlled clinical trial literature published up to March 2015. Two reviewers independently selected the studies and performed data abstraction and validation.

Background: Depression is a mental health disease of growing public health concern because depressive mood affects the sufferer's daily life and is also associated with productivity decline. Depression that is caused by other diseases or substances is referred to as secondary depression, which is an important distinction because curing the underlying cause could subsequently regulate depressive mood. Empty nose syndrome (ENS), also known as "paradoxical obstruction of the nose," is a condition in which the major symptom is difficulty breathing, despite having sufficient breathing space in the nose.

This study examined the effects of intrathecal areca nut on spinal nerve-ligated and chemotherapy-induced neuropathic pain (NP), and investigated the relevance of spinal 5-hydroxytryptamine (5-HT) and α2-adrenergic receptors to those effects. For drug administration, intrathecal catheters were inserted into the subarachnoid space of male Sprague-Dawley rats. NP was induced either by spinal nerve ligation (left spinal nerves L5 and L6) or by chemotherapeutic injection (intraperitoneal cisplatin, 2 mg/kg/day, once daily for 4 days).

Background: Chronic pain reportedly exerts complex effects on immune function. Natural killer (NK) cells are lymphocytes that play a critical role in cellular and innate immunity. This study examined changes in the subset populations and cytotoxic activity of peripheral blood NK cells in patients with chronic pain.

Background: Administration of arginine vasopressin (AVP) is associated with reducing jugular venous (SjvO) and regional cerebral (rScO) oxygen saturation under propofol-remifentanil (P/R) anaesthesia. We determined whether background anaesthetics modulate the effect of AVP on cerebral oxygenation and haemodynamics.

Methods: We randomly allocated 60 adult patients scheduled for shoulder surgery in the beach chair position (BCP) into 4 groups, to receive either an intravenous bolus of saline (groups PR-S and SN-S) or 0.

Purpose: This study was a systematic review to evaluate the effects of aromatherapy on menopausal symptoms, perceived stress and depression in middle aged-women.

Methods: Eight databases were searched from their inception September 8, 2015. Two reviewers independently performed the selection of the studies, data abstraction and validations.

Article Synopsis
  • Intraoperative opioids can lead to opioid-induced hyperalgesia (OIH), an increased pain response, potentially involving NMDA receptors; this study investigates the effects of nefopam and ketamine on postoperative pain and OIH in patients receiving remifentanil during surgery.
  • A total of 54 patients undergoing laparoscopic cholecystectomy were divided into three groups: one receiving nefopam, one receiving ketamine, and a control group with standard anesthetics, with postoperative pain and sedation levels measured.
  • Results showed that both nefopam and ketamine reduced the need for intraoperative and postoperative opioids, but nefopam was more effective in managing pain and sedation than ketamine.

Recently, we reported that (AA) has anti-adipogenic properties and in . Reduction of adipogenesis by AA treatment may dampen systemic inflammation and protect neurons from cytokine-induced damage. Therefore, the present study was undertaken to assess whether AA increases neuronal maturation by reducing inflammatory responses, such as those mediated by cyclooxygenase 2 (COX-2).

Human health problems due to long life are becoming major issues in society, and in particular greater interest collected on women's health after menopause. Many substances can be introduced to women's health, however, materials from the substances have not shown all of the safety and efficacy properties that are not easily found. Currently, it is known about the effects of the disease on the female insect-derived material that is capable of overcoming this problem significantly.

Background: Bone cancer pain has a disruptive effect on the cancer patient's quality of life. Although ginsenosides have been used as traditional medicine in Eastern Medicine, the effect on bone cancer pain has not been thoroughly studied. The aim of this study was to determine whether ginsenosides may alter the bone cancer pain at the spinal level.

The Notch signaling pathway is an important cell signaling system, which regulates cell differentiation, proliferation, and apoptosis, and is aberrantly activated in a wide range of cancer, including ovarian cancers. However, it remains unclear as to whether Notch signaling plays a role in the progression and prognosis of ovarian cancer. We examined the mRNA and protein expression of Notch 3, Jagged 1, and Jagged 2 in 98 ovarian epithelial tumors via real-time PCR and in 175 tumors with immunohistochemical analysis, and then correlated their expression levels with clinicopathological parameters and patient survival.
